MORTAR-MIXER.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed December 17, 1910. Serial No. 597,832.

' To all whom it may concern:

Be it known that I, GUSTAVE CARLSON, a subject of the King of Sweden,residing at Plainfield, in the county of Union and State of New Jersey,have invented new and useful Improvements in Mortar-Mixers, of which thefollowing is a specification.

This invention relates to concrete and mortar mixers, and its object isto provide a cylinder for mixing the mortar and have it carry a spoutinto which'may be delivered the contents of the cylinder so that acertain amount may be delivered through the spout, and when the desiredamount'has been delivered the spout may be so turned as to shut off thesupply while the mixer continues to revolve, as will be more fullydescribed in the following specification, set forth in the claim andillustrated in the drawings, wherein,-

Figure 1 is a front view of the mixer.

Fig. 2 is a side elevation of same. Fig. 3 is a cross sectional viewlooking toward the spout. Fig. 4 is a longitudinal sectional view.

The mixer is mounted on a frame 5 of any desired shape or construction,and has a substantial base 6 preferably of wood. The frame carries thejournal boxes 7 in which rotates a shaft 8. This shaft 8 has secured toit the hub 9 from which radiate spokes 10 which carry the cylinder 11.This cylinder may be provided with the grooved ring 12 for the drivingband 13 and it is open ateach end. Within the cylinder are buckets 14which are adapted to carry the material up the sides of the cylinder soas to deliver it into the chute or spout which is secured to I a sleeve16,mounted on the shaft 8. It will be seen that the buckets 14 aresubstantially uniform at the discharge end of the cylinder, while at thefeed end they may be made in various shapes as their ob ect at this endis simply to agitate and mix the material. The sleeve 16 is providedat-its outer end with a flange 17 carrying a handle 18. All of the viewsshow the side in its position to deliver the mortar at the front of themachine, but when it is desired to render this spout inoperative andstop the delivery of the material, the sleeve 16 is rotated reversingthe direction of the spout 15 and preventing the delivery of thematerial into it. At the rear end of the cylinder is a chute 19 intowhich the component parts of the mortar is thrown for the purpose ofmixing same.

It is obvious that the device may be otherwise modified and the partsdifierently arranged without departing from the essential feature aboveshown. It is also evident that this invention need not be confined tothe mixing of concrete or mortar but may be used for many other purposeswhere plastic materials are to be mixed such as fertilizers, grout,mortar and where a ready means for delivering same may be required.

What I claim as new and desire to secure by Letters Patent, is,

In a device of the class described, a support, a horizontal shaftjournaled in said support, a hollow drum surrounding said shaft andcentrally attached thereto, said drum provided with end openings, asleeve member rotatably and slidably mounted upon said shaft andextending into the drum, means whereby said sleeve may be operated, anda discharge chute provided with a central opening for the reception ofsaid sleeve member, said chute being fixedly attached to said member inan inclined position with respect thereto and extending into the drum. 1

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES F. DUHAMEL, CHARLES LA RUE.
